摘要:

工作模式识别是通过对信号的处理分析来确定雷达功能和行为状态的,是情报侦察、电子对抗领域的重要手段之一。随着现代机载雷达功能的多样化,其对应的信号样式也变得越来越复杂,而且日益复杂的侦察环境也导致侦察信号的质量参差不齐,这些都给传统的工作模式识别方法带来了巨大的困难。针对这一问题,在现有工作模式识别方法的基础上,提出了一种参数特征识别与D-S证据理论识别相融合的工作模式识别方法。首先,对于各侦察机处理得到的辐射源特征信号,利用特征参数识别算法快速得到工作模式信息,并结合D-S证据理论对识别结果加以验证。其次,对于单平台无法识别的信号,采用D-S证据理论融合识别的方法来完成工作模式的判别。从理论分析可以得出,该识别算法具有运算速度快,结构简单等优点,且新的融合识别方法可以提高工作模式的识别精度。最后,仿真验证了此方法的可行性。

Abstract:

Operational pattern recognition is one of the important means in the field of intelligence reconnaissance and electronic countermeasures,which is to determine the function and behavior of radar through signal processing and analysis.With the diversification of modern airborne radar functions,the corresponding signal styles are becoming more and more complex,and the increasingly complex reconnaissance environment also leads to the uneven quality of reconnaissance signals,which brings about great difficulties to the traditional operational pattern recognition methods.To solve this problem,based on the existing work pattern recognition methods,a new work pattern recognition method is proposed,which integrates parameter feature recognition and D-S evidence theory recognition.First,for the radiation source characteristic signals processed by each reconnaissance plane,the feature parameter recognition algorithm is used to quickly obtain the working mode information,and the recognition results are verified by the D-S evidence theory.Second,for the signal that can not be recognized by a single platform,the method of D-S evidence theory fusion recognition is used to distinguish the working mode.From the theoretical analysis,it can be concluded that the algorithm has the advantages of fast operation speed and simple structure,and that the new fusion recognition method can improve the recognition accuracy of the working mode.Finally,the feasibility of the method is verified by simulation.
